Google Chrome zero-day used in the wild to collect user data via PDF files

A security firm said this week that it discovered malicious PDF documents exploiting a Google Chrome browser zero-day. The vulnerability allowed attackers to collect data from users who opened PDF files inside Chrome’s built-in PDF viewer.

Exploit detection service EdgeSpot, the company that found these malicious files, says the PDF documents would contact a remote domain with information on the users’ device –such as IP address, OS version, Chrome version, and the path of the PDF file on the user’s computer.

This phone-home behavior did not take place when researchers opened the same PDF files in desktop PDF viewer apps, such as Adobe Reader and others, but was limited to Chrome only.

The company said it spotted two distinct sets of malicious PDF files exploiting this Chrome zero-day, with one series of files being spread around in October 2017, and the second set in September 2018.

The first batch of malicious PDF files sent user data back to the “readnotify.com” domain, while the second sent it to “zuxjk0dftoamimorjl9dfhr44vap3fr7ovgi76w.burpcollaborator.net.”

There was no additional malicious code in the PDF files that EdgeSpot discovered. However, collecting data on users who open a PDF file can aid attackers in fine-tuning future attacks and exploits.

Researchers said they notified Google over the Christmas holiday, last year, when they first discovered the documents. The Chrome team acknowledged the zero-day and promised a fix for late April.

“We decided to release our finding prior to the patch because we think it’s better to give the affected users a chance to be informed/alerted of the potential risk, since the active exploits/samples are in the wild while the patch is not near away,” researchers said in a blog post yesterday.

The blog post also contains samples and indicators of compromise (IOCs) for the malicious PDF files the company discovered.

Until a patch is out, EdgeSpot is recommending that users either use a desktop app to view PDF files or disable their internet connection while they open PDF documents in Chrome.

In unrelated research, but also connected to the world of PDF documents, earlier this week, security researchers revealed vulnerabilities that allowed them to fake signatures on 21 of 22 desktop PDF viewer apps and 5 out of 7 online PDF digital signing services.

Key Criteria for Evaluating Unified Endpoint Management

Published

on

Endpoint management is one of the most significant challenges in the enterprise today. An increasingly large percentage of our workforce is distributed and demands flexibility to work wherever they want, whenever they want. We must respond by giving them access to the services they require to do their jobs effectively. The alternative is that we, as a business, will suffer, lose good people, and become less competitive. However, we must achieve this essential access while maintaining security and control of our business’s data assets.

An appropriate endpoint management strategy is key to addressing these issues. Our approach should be holistic and unified, bringing together control of devices, management of applications, security of data, and access controls.

Unified endpoint management (UEM) is the approach to meeting this challenge. It has evolved from traditionally disparate solutions for endpoint management, application delivery, and security into a single platform. This single platform delivers a consistent end-user experience across all devices, applications, and locations while maintaining security and control of data assets. The leading solutions allow us to enroll devices easily into our control, provide support, and ensure constituency and compliance while managing access to our applications and data.

This GigaOM Key Criteria Report describes UEM solutions and identifies key criteria and evaluation metrics for selecting such a solution. The corresponding GigaOm Radar Report identifies vendors and products that excel in this sector. Together, these reports give decision-makers an overview of the market to help them evaluate existing platforms and decide where to invest.

How to Read this Report

This GigaOm report is one of a series of documents that helps IT organizations assess competing solutions in the context of well-defined features and criteria. For a fuller understanding consider reviewing the following reports:

Key Criteria report: A detailed market sector analysis that assesses the impact that key product features and criteria have on top-line solution characteristics—such as scalability, performance, and TCO—that drive purchase decisions.

GigaOm Radar report: A forward-looking analysis that plots the relative value and progression of vendor solutions along multiple axes based on strategy and execution. The Radar report includes a breakdown of each vendor’s offering in the sector.

Solution Profile: An in-depth vendor analysis that builds on the framework developed in the Key Criteria and Radar reports to assess a company’s engagement within a technology sector. This analysis includes forward-looking guidance around both strategy and product.

High Performance Application Security Testing – Cloud WAF Security Platforms

Published

on

This free 1-hour webinar from GigaOm Research features analyst Jake Dolezal and will focus on comparing Web Application Firewall (WAF) security platforms in an enterprise with high performance needs.

This webinar will discuss web application security mechanisms deployed in the cloud. The cloud enables enterprises to differentiate and innovate with microservices at a rapid pace. However, the cloud is just as vulnerable, if not more so, to attacks and breaches as on-premises APIs and apps are. Our focus is specifically on approaches to securing apps, APIs, and microservices that are tuned for high performance and availability. We define “high performance” as companies that experience workloads of more than 1,000 transactions per second (tps) and require a maximum latency below 30 milliseconds across the landscape.

In this webinar, we will reveal the performance tests of security mechanisms on NGINX, AWS, and Azure, specifically: ModSecurity, NGINX App Protect WAF, AWS Web Application Firewall (WAF), and Azure WAF.
